正在尝试从我的本地电脑运行websocket服务器

Question

我正在尝试为我的UWP Windows 10应用程序开发一个web套接字服务器应用程序。

这是我的代码：

class Server
{
    public  async void Start()
    {
        MessageWebSocket webSock = new MessageWebSocket();
        //In this case we will be sending/receiving a string so we need to set the MessageType to Utf8.
        webSock.Control.MessageType = SocketMessageType.Utf8;
        //Add the MessageReceived event handler.
        webSock.MessageReceived += WebSock_MessageReceived;
        //Add the Closed event handler.
        webSock.Closed += WebSock_Closed;
        Uri serverUri = new Uri("ws://127.0.0.1/motion");
        try
        {
            //Connect to the server.
            await webSock.ConnectAsync(serverUri);
            //Send a message to the server.
            await WebSock_SendMessage(webSock, "Hello, world!");
        }
        catch (Exception ex)
        {
            //Add code here to handle any exceptions
        }
    }
    //The MessageReceived event handler.
    private void WebSock_MessageReceived(MessageWebSocket sender, MessageWebSocketMessageReceivedEventArgs args)
    {
        DataReader messageReader = args.GetDataReader();
        messageReader.UnicodeEncoding = Windows.Storage.Streams.UnicodeEncoding.Utf8;
        string messageString = messageReader.ReadString(messageReader.UnconsumedBufferLength);
        //Add code here to do something with the string that is received.
    }

    //The Closed event handler
    private void WebSock_Closed(IWebSocket sender, WebSocketClosedEventArgs args)
    {
        //Add code here to do something when the connection is closed locally or by the server
    }
    //Send a message to the server.
    private async Task WebSock_SendMessage(MessageWebSocket webSock, string message)
    {
        DataWriter messageWriter = new DataWriter(webSock.OutputStream);
        messageWriter.WriteString(message);
        await messageWriter.StoreAsync();
    }
}

此处出错：等待webSock.ConnectAsync（serverUri）

出现此错误：

未找到（404）。（HRESULT异常：0x80190194）

我对它没有任何个人经验，但您可能想试试IotWeb HTTP服务器。它似乎是一个便携式嵌入式HTTP和web套接字服务器，也支持UWP，可以在Windows Store和Windows 10 IoT Core应用程序中运行。

从它的存储库来看，它相当新，并不完全成熟，也没有很多可用的文档或样本。不过，还有一个NuGet包可用。

不幸的是，我还没有找到其他选择。

代码

await webSock.ConnectAsync(serverUri);

是尝试连接到ws://127.0.0.1/motion上的现有服务器，而不是在此地址上部署服务器。

您可以在以下链接中寻找构建c#WebSocket服务器的方法：
